CPU Idle Temp Too High

[litegrace]

Hi guys, I just finished my first PC build and when I booted into the bios (MSI Gaming 5 motherboard), it said my CPU (i7 4790k with stock cooler, non-overclocked) was at 55 C and it rose to 62 C within a couple minutes, despite it only being in the bios and never run before. Any ideas what the problem is? I'm afraid my CPU is going to melt if I do anything on it at this point. I've double checked that the fan is all the way pushed in and it says it's running at 1400 rpm trying to cool the CPU. I honestly don't know what to do, I'm worried.

Does anyone have any suggestions? Thermal paste was already applied and I didn't mess with it, so that shouldn't be the problem either. I just really don't know what to do at this point. I have the side of the case open so air flow definitely isn't a problem right now. Also, should I be able to feel heat coming from the CPU at this temperature? It's been running Windows 8 for like 15 minutes now and nothing feels hot inside of my case. It's ever so slightly warm, but barely more so than the room temperature. I'm just curious if the CPU really is that hot or if a sensor is bad.

Thanks guys, I'll probably go with the Hyper 212 Evo and some Noctua case fans. Just wanted to update on my CPU issues as well. After determining that the thermal compound that came with my stock cooler was bad, I bought a cheap tube of Antec thermal compound (temporary, all they had at best buy) to re-apply it and test the cpu again. It made quite a big difference, but still was getting into the 90's when editing video or doing anything CPU intensive. Intel offered me an overnight CPU replacement (which is now installed) and the initial results are much better.

I'm getting 38-42 C when idle (still stock cooler), and I tested the Valley benchmark to test my GPU and how hot my CPU would get when stressing my rig on more demanding games. Nothing is overclocked and on Extreme HD settings I got an average FPS of 57.0 and a score of 2385 which I'm happy about (single 970 GPU). GPU hit 62 C max with 60% fan speed and the CPU hit 74 C max, which is great for stock cooling and a lack of good case cooling for right now.

Sounds good.

So I've been on my computer a while now (mostly watching YouTube and Twitch) and decided to install a game on Steam (DC Universe Online, I game I play often). I'm getting a great framerate (in the 100's) but my CPU is hitting 80 C. Is this to be expected with a stock cooler or does this still seem to high? It just seems pretty high to me, but I might just be paranoid at this point. I closed up my case and room temperature is about 26 C right now, which isn't ideal. Should I be worried at all?

 

[i7Baby]

No. I'd expect 60 maybe 70C max I still think there's something screwy with your stock cooler or how its been mounted. Get the hyper 212 evo and it should drop below 60C gaming and 40C at idle.

I hope so, I'm tired of worrying about my CPU overheating. I'm starting to think that maybe the thermal compound Intel uses isn't good or it's applied poorly because I'm actually getting slightly higher idle and load temps with this CPU than I was with the previous one (after having replaced the thermal for the first one). I know a big problem right now is also the fact that my case has no intake fan, but that's why I've been removing the side panel to allow for better airflow until my Noctua's get here. Hopefully once I install those and the 212 it will make a huge difference, if not then I'm pretty disappointed in this processor. I don't see how a CPU can be built for overclocking yet overheat during non-demanding games while not overclocked, seems silly to me.

Also, quick observation: I've noticed that there is a hot spot right between my GPU and CPU (toward the top back, by my exhaust fan) and I think that's because my GPU blows it's air up toward that spot (and the CPU), any chance that could be causing issues? I ran the Valley benchmark and the GPU never even hit 70 C (fans only hit 60% of their max rpm), so it's not running hot but it's pushing the heat it generates up to the CPU. Not sure if I can do anything about this, but I'll probably add a Noctua in the bottom front for intake, replace the stock fan in the top back with a Noctua for exhaust, and maybe even add the stock fan on the top for a second exhaust. Any thoughts on this? I'm starting to think that maybe my setup (mainly the lack of an intake) might be causing a lot of my heat issues. Sorry again for all the long posts.

Make all those changes. If still a problem post a new thread.

Thanks for all the help, I'll pick you as best solution and make a new thread if I run into any problems like you said.

i have the same problem. but mine is worst. i reached 80c on idle. amd a6 is my cpu. i only play nba 2k14 and it lags even with gt630 gpu. i dont know what is happening inside my system unit. but it's getting really hot.

In the bios the processor is running full speed and around 80% load.
Once into windows it will activate speed step and the processor will idle .
At this point temps will drop dramatically.
Also it takes a few times running for the stock thermal paste to melt and become thinner and work better.

THANK YOU!!! I know thisa is a rather old post but I just happen to have a i7-4790K (Devils Canyon) mounted to a MSI Z97 MPower MAX AC. Had an Asrock Z77 Extreme4 and i7-2600K which I replaced with the MSI mobo about 3 or 4 months ago.

I'm running advanced liquid cooling and My Asrock/2600K combo idled at 28C-30C so I was VERYsurprised the very first time I fired up the MSI UEFI and saw that CPU Temp So high! I never could understand why that was because every independent CPU temp monitor software I ran when booted to the OS, said the MSI/4790K combo was idling at 32C.

The difference between the USFI temp and the other monitor temp reports were huge yet, all the independent monitor software I had installed, (about 4 different programs), matched each other with a temp variation of less than .5C.

Finally, even though most people say to go by the UEFI temp over all others, I had to assume that my MSI UEFI was not reporting the temp accurately or perhaps, was displaying a Fahrenheit scale even though it was set for Celsius.

This always 'nagged at me' in the back of my mind until I ran into your post here, (and several others in other websites), which confirm that my UEFI temp is accurate. It does actually match my software temp reports when I set the CPU to run wide open, (in this case, as high as 4.95GHz).

So thanks for getting this little nagging issue off my back. I know that I should have thought to browse this point long ago but it was only now that I did because I finally just spliced the mobo cooler into the cooling loop today and well, here I am.
